he invention further aims to provide a. burner including 'a tubular body'to which lany size of burner head may bel connected. For instance, various burner heads may be provided having different diameters of passagestherethrough for the jet of il and for spraying effects and therefore the heads are interchangeable according to the `requirements, in fact, according to the size of' boiler tor vother device to be heated. While the designand construction at present illustrated and set erable, duction of the invention to a more practical form for commercial purposes, the invention forth are deemed prefit is obvious that as a result rifareprovided they thejets of steam, 1n order to provide various lThe invention comprises further features and combination of arts, as hereinater set forth, shown in the. rawings and claimed.

. I10o line of single means forcreatinlgl a whirlingspray Referring more specially to the drawings, 1 designates a tubular body lwhich may be of any suitable length 'or any diameter thatmay be found convenient, and 2 denotes a second tubular body of a relatively smaller diameter whereby it may extend into the main tubular body so as to afford a steam space 3 intermediate the walls of the two- 4 has an annular recess 5 which so engages the end of the dominant body as to hold the ange concentric with the outer body 1, thereby holding'the inner tubular body correspondingly concentric. The portion ofthe flange 4 which extends into the outer body 1 is threaded .into said body, as shown at 6, to insure a tight joint. However, the threads may be dispensedwith, if desired just so.

long as the flange is drawn tight against the end edge of the outer tubular body 1. A

suitable'packing 7 is provided. Also, if desired, the packing may be dispensed with.

The flange 4 at'points diametrically opposite each other relatively to the circular interor of the auxiliary tubular body 2 is pro vided With apertures or openings 8. These openings or apertures act to direct jets of 'steam at angles toward each other so that the jets of steam may'impinge at a point ccntrally of the vapor or the combined mixture of steam' and oil as it leaves the interior of the auxiliary' tubular body 2, thereby more thoroughly atomizing the mixture. The flange 4 is provided with additional openings or apertures 9. While certain of these openings 9 are diametrically opposite certain other .openings 9, they are disposed upon like inclinations relatively to each other, butwhich inclinations are at angles:

to the axis of the passage through the auxiliary body. In other words, the apertures or openings 9 are constructed at angles to the apertures or openings 8, and these openings 9 tend to direct a plurality of jets of steam through the mixture as it leaves the inner auxiliary body, thereby thoroughly atomizing the mixture. It will be noted that certain of the jets of steam will impinge with certain other jets of steam that emanate from the various openings 9. The diametrically opposite openings 8 will cut directly through the mixture While the jets of steam emanating from the openings 9 will cut through the mixture at various angles to the axis of the center of the mixture, that is, as it leaves the mixing chamber 10 of the vauxiliary tubular body inasingle volume.

The outer casing,or tub ar body 1 has a lateral tubular extension 11 which may form a part of the body 1 or be threaded thereinto as shown, though not necessarily, for it is obvious that this extension 11 may be otherwise suitably connected. Any suitable steam supply tube may be connected to the extension 11 to supply steam to the rear part 12 of the steam chamber.

A T-union 13 is mounted on the interior of the dominant tubular body and threaded into one end of the union is a nipple 14 which is also threaded into the head plate 15 which is similar in constructionto the flange 4 of the inner. tubularv body 2. In fact, this head plate 15 may be fitted frictionally into the end of the dominant tubular body or threaded thereinto as the case may require. A closure or cap 16 is threaded on the end of the nipple 14 for the purpose of closing the same. l

A coupling 17 is threaded into the union 13 and in turn is threaded at 18 tothe oil tube 19. This oil tube 19 has a nozzle 20. A portion of the tube 19 adjacent the nozzleA 20 is threaded through the end head 21 of the auxiliary tubular body2. By tightlening up on the nipple and adjusting the coupling 17 accordingly, the flange 4 of the l auxiliary tubular A'body and the head platev 15 may bedrawn securely and tightly in position, thereby affording fluid-tight joints between the parts. A T-union 13 has threaded thereto a tubular coupling 22 to which any suitable oil supply pipe (not shown) may be connected. This coupling 22' holds the union 13 from rotating.

The end head 21 of the auxiliary tubular body is provided with a plurality of openings or apertures 23 which arev correspondingly inclined, that is, relatively to the center of the end head. In fact, these openings 108 23 are arranged Iapproximately tangentially to the center of the end head, but are also arranged yjust opposite to the arrangement of the openings 9, so as to provide a whirling spray of steam impinging with the jet 110 of oil from the nozzle, the whirling of thespray being just the opposite to the whirling of the spray emanating from theopenings 9. It will be seen that while the oil is thoroughly broken up and atomized in the first y instance by the whirling spray of steam within the mixing chamber 10, the mixturey as it leaves the chamber 10 is again and more t'horoughlyatomized due tothe second whirling spray, just the opposite to the first. whirling spray. l

In addition to the openings 23, the end head 21 has two diametrically opposite openings or apertures 24, so that the jets of steam Will be directed at angles toward each other and impinge with each other directly in the center' of the jet of oil emanating from the nozzle, thereby thoroughly breaking up the globules of oil, so that they may be further a-tomized rby means of the whirling lspray o from the openings 23 will be projected tan-4 .the pipe or ot er connection,

-nect'ed to the extension' 1 1, and then into the steam. The openings 24 are arrangedadj'acentlthe tapered extension 25 'of the end head'lso that the jets of steam will be projected along the face of the extension, the `other .-jets of. steam emanating.

while gentially with relation to the extension'25f As previousl stated, steam enters through which is conp chamber' 12, thorouohly illingthe chamber and particularly vfil ing that portion of the chamber vbetween the inner and outer tubular casings. The steam will emanate from .the openings 23 and 24 and from the openings 8 and 9.' Oil is supplied to the tube 19 through the coupling 22 and then will emaform of burner.
